This application claims the priority of U.S. Provisional Patent Application Ser. No. 60/725,343, filed Oct. 10, 2005. BACKGROUND OF THE INVENTION

The invention relates to clamps that are used to hold different parts together after they have been glued together or prior to being welded or soldered together. More specifically the invention relates to an angle clamp that can be used with C-clamps, sliding arm clamps, locking pliers and other locking devices.

In assembling panels, boards, pipes, etc. it is important that the respective parts be oriented properly together. This is especially true where these parts are held together by adhesives or by soldering or welding. One of the most commonly used types of clamps are C-clamps. Another is the sliding arm clamp. Locking pliers and vice grips are also used. There has been a need for a unique angle bracket that can be used with the above mentioned clamps and locking devices and one that can be used with an array of attachments that make the assembly process easier.

It is an object of the invention to provide a novel angle bracket that is multi-functional in its ability to serve more than one application.

It is also an object of the invention to provide a novel angle bracket that allows for a minimum time for set-up.

It is another object of the invention to provide a novel angle bracket that is compatible with interchangeable accessories.

It is an additional object of the invention to provide a novel angle bracket that is economical to manufacture and market.

SUMMARY OF THE INVENTION

The novel angle bracket is made of a block of material that may be plastic, metal or any other suitable material. It has an elongated upper arm member, an elongated lower arm member and a connecting member. The rear surface of the respective upper arm member and lower arm member are oriented at 90 degrees to each other. The front surface of the respective upper arm member and lower arm member each have a generally circular recess with a central aperture that passes all of the way through to the rear surface of their respective arm members. A plurality of locking channels radiate outwardly to the edges of the respective arm members from the circular recess.

When used with C-clamps and vice pliers, the swivel pad of these respective tools would be positioned in the circular recess and the arms of these tools would drop into the locking channels thereby preventing rotation of the clamping tool. The rear surfaces of the respective upper and lower arm members has a longitudinally extending V-shaped groove that allows circular tubes or pipes to be clamped to the rear surface of the angle bracket. One of the side edges of the angle bracket has an ear member extending laterally from each of the upper arm member and the lower arm member. A pin is mounted in the bottom surface of the ear members and these pins act to alignment the side edges of parts that are being clamped together. These pins may be spring loaded, or solid rods, and they be removable when not being used.

An alternative embodiment angle bracket has been designed for use when assembling pipes that will interconnect to each other at angles by use of an elbow pipe. This angle bracket has an L-shaped upper clamp arm that is pivotally connected to an L-shaped lower clamp arm. These clamp arms rotate about a pivot pin that can be tightened to lock their orientation at any predetermined angle. A V-shaped support clamp portion is formed on the free end of each of the respective L-shaped upper and lower clamp arms. These V-shaped support clamp portions provide a support structure for the individual pipes that are being connected together. A tab extends laterally from a support wing member of each of the V-shaped clamp portions. This tab has an aperture that allows the rod of a sliding arm clamp to be adjusted longitudinally there within. An adjustable arm is also slidably mounted on the rod member and its one end has a swivel pad mounted on a threaded bolt that is used to clamp a pipe member rigidly into the V-shaped support clamp portion.
